Device Removed in 2020 & Account Closed - 8 Months Later still doing debit orders off my account

My contract ended September 2020 - called Netstar to come and remove the device and close my account. They came the next day and removed the device. I stopped receiving log books.

8 Months Later they are still debiting my account - have called call centre numerous times and every time they say there is no record of the account being closed/cancelled - but they can see the device was deactivated in Sept 2020. Their supervisor will call we back - has not happened once. According to them, they don't have any record of my call to even remove the device, nor my numerous calls after to get this sorted AGAIN.

Very poor excuses to basically ***** money for no services.

Why on earth would anyone still pay for services not rendered?
